NSX Edge Datapath in NSBU (Networking and Security Business Unit)

10/40/100 Gb Enterprise and Cloud Switches

• Lead engineer participating in all aspects of product design and implementation.

• Currently working on 25/50/100 Gb cloud / datacenter ToR switch.

• Responsible for the overall management infrastructure of the switches.

• Working on environmental monitoring, logging, fault and alert management,

and secure authentication. Supporting service requirements.

• Designed and prototyped multi-chassis link aggregation feature; lead productization and

integration with third party stack. Overseeing migration to vendor supplied solution.

• Responsible for ILOM (Integrated Lights Out Manager) across the switch product line.

• Ported the embedded ARM firmware to work as software processes on 64bit Intel processors

under Oracle (Red Hat) Linux.

• Cooperating with account teams on pre-sales engagement as well as support.

• Security Point of Contact for Oracle's Ethernet swtiching products.

Responsibilities include enforcing of secure coding standards and making sure that security

related bugs are fixed in a timely manner.

10 Gb Enterprise Switches

• Worked on Ethernet fabric for high performance computing.

• Automated discovery and configuration of ToR and blade chassis switches in a Clos topology.

Netra Data Plane Software

• Cooperated with a third party vendor to create development system for Sun CMT processors.

• Responsible for the virtualization aspects using the Sun CMT hypervisor software

• Implemented a shared memory IPC across domains.

• Worked on reference applications for packet forwarding.

• Involved in customer engagements and conducted training sessions for engineering groups.

• Collaborated with researchers from the Barcelona Supercomputing Center on scheduling strategies for packet processing.

CMT Processor

• Lead cross BU team to design an XML offload engine. Team consisted of engineers from web services, performance engineering, processor design, and networking.

• We designed and implemented a system that combined resources of the network interface unit, dedicated parsing hardware, and software, to offload the bottom layers of XML processing in the web services stack.

Load Balancer

• Architect for L7 load balancer (Sun Fire B10n) in Sun's blade chassis.

• Load balancing blade consisted of a multi-core network processor, pattern matching hardware, and a MIPS CPU for management. The overall system also contained an SSL proxy blade and host components in Solaris and Linux, to facilitate direct server return and monitoring.

• Designed and implemented an efficient memory management system to share buffers between NPU cores and the CPU.

TCP/IP Offload Engine and 10Gb Ethernet Infiniband HCA

• System design included hardware for fast path and a VLIW processor for slow path processing.

Gigabit Ethernet L4 Switch

• Involved in many aspects of the networking stack, an emulator for the switch chips, and the design of an L2 multipathing system to alleviate spanning tree limitations.

• Responsible for TCAM entry management.
